` .IMPROVEMET IN CULTIVTRS.

` VThe Schedule referred to in these Lettere Patent and making paxt of the name;

To L`all @dimm it ma/y concern;

Be it known that LJ. `McILvAnI,-of Tennessee, in

` the county of McDonough, and State of Illinois, have iu-y vented new and useful `Improvements in Cultivators;

and I do hereby declare that' the following is `,a full and 4exact description of the same, reference being'had to ythe accompanying drawings,iand tothe letters of reference marked thereon. y

` This invention relates tocultivators, and consists,

mainly, in certain details `of construction, which will be fully described` hereinafter, by `means of which a more efticientand desirable machine is produced.

'I term this machine the f Hancock Cultivator.

Inwthe drawings- Figure 1 represents a side view, and

. Figure 2, a plan view of my improved cultivator.

Figure 3, sheet `2, represents a plan view of kone cultivator, with certainmodications' `of construction.

" "Figure 4, a side elevation of the same.

To enable those skilled .in the art towhich my invention appertaius, to make and use the same, I will now proceedtodescribe its construction and operation. A represents the axle .of the machine, rest-ing upon the wheels A', which is curved, as shown, to give sufn iicientroom beneath ithef'plows,

for--the necessary movement of B lB1 represent a frame resting upon theaxle A, and extending forward, as shown, to which is attached i `the*pole B".

Hanging from the front beam B, of the iianie, a`re `the peculiar-shaped beams 0, whichform both upf rights and braces, and which areeonstructe'd of a sin- `gle piece of wrought-iron.

The 'upper end ofthe .uprightpart of `these beams is secured in 'asocket by 4means of a bolt, as shown, f bywhich arrangement, a connection of great stiffness `is made. L The rear end of the brace-part of the beam is securely'attaehed beneath the axle, as shown. f 'By means of holes in'the l tter, and sockets in the front beam of the frame, the beams U are easily adjusted for cultivating different wMidths of rows.

D represents the plow-beams, to which the plows` are attached.` f i on their front endsto the beams' 0, as shown, by meansof the clevis d, suitable holes "pbeing made in theformerfor adjusting the plows for workingat different depths.. i

By means of this attachment, thel plows can be 7 easilyswung to one side, if desired, the beam turning upon the bolt which attaches `it to the clevis, orthe plows may be elevated, the clevis"turning upon the bolt which attaches it to the standard.

The rear ends of the plows are f elevated, when def-y sired to move tofand from the field, by means of thev chains` d', which catchwithin the hooks upon theup- `per beam o i' the frame,'as shown.

`It will` be observed, thatthe plows are peculiarly F arranged in regard to the bearmthe frontrplow being I placed upon the inside lof the beam, the middle plow beneath the beam, and the rear plow upon the out:.

H represents an adjustable seat, whichl slides upon l the centre-bar of the frame, as shown, and which may `be drawn out when wanted for use.

The arrangement of this is such, that when the plowmau is seated thereon, the corn canbe easily seen.

By the construction and arrangement herein described, an eiieient machine is produced. It is sim-f plein constructiombeing composed of few parts, and,

at the' same time, it is exceedingly strong and du'rable. i The operation will be easily understood.

The front ends of the plows having been properly adjusted, by the means described, (the distance between the beams G having been previously regulated motion is communicated to the machine. i

`The plowman now swings the plows from side to side, or elevates them, as circumstances may require,

Veither riding or walking, as hemay choose.

In sheet 2 is shown one cultivator, with certain modifications of construction, which will now be described. i

I I represent beams, corresponding to beams G in sheet l.

YInstead, however, of being attached tothe front beam in the manner before described, they may be provided with an arm, extending, at right angles, in aninward direction, which arm rests upon the beam, as shown.

The end of this arm is provided with' arhole for the Yreceptionof a bolt.` i

t' represents a short arm, provided with a slot, and `havingalso a hole for the reception of a bolt, which is slipped over the standard I, before it is placed in position.

. t" represents the bolt, by means of which the fastening is completed, as is clearly shown in the drawing. By this arrangement, the beams are vfirmly held, while, at the same time, their rear ends are permitte to swing laterally, it' desired.

The `rear ends of the braces I are held by bolts J, the'heads of which are caught in Arecesses in the beam K2, the axle-plate being slotted for that purpose.

This slot extends inline with the axle, as shown,

and thus permits lateral adjustment of the braces, by means ofwhich the position of the' p lowis changed.

For thepurpose of adjusting, also, the chains,

which hold the rear ends of plow-beam, I provideY the screwhooks K, which may be moved laterally in the slots k, in the cross-beam K1.

I representsthe seat, which is attached to the seatarm L', by means of the bolt l.

The armv L is slotted, for the purpose of permitting the seat t-o be adjusted forward or rearward, as may be desired.

The`seat-arm is secured in place by means of the pin m, which rests in a corresponding socket in the end of the tongues, and a band, n, as shown.

By elevating the seat until the pin is lifted out of the socket, it may be displaced by drawing it back.

Having thus fully described my invention,
